【偷懒计划】家里的笔记本懒得开虚拟机了，开个虚拟机啊卡的要死不划算，so在windows装一个

0.简介

这里以部署2.1.1作为介绍，下载hive3.+版本后，需要加上一个步骤，就是把hive2.x版本的bin目录下哪些cmd文件拷贝到3.x版本里面去，就可以在windows下直接用了，hive3的基本配置和2.1.1差不多，不过多介绍。

1.解压

http://archive.apache.org/dist/hive 下载hive包后解压，然后新建个文件夹my_hive

myhive里面建几个文件夹

然后把mysql驱动丢进lib里面

配置文件

首先改名字
hive-default.xml.template -----> hive-site.xml
hive-env.sh.template -----> hive-env.sh
hive-exec-log4j.properties.template -----> hive-exec-log4j2.properties
hive-log4j.properties.template -----> hive-log4j2.properties
对了，没有hive-site的童鞋把hive-default.xml复制一份叫hive-site。xml即可
然后配置

修改 hive-env.sh

# Set HADOOP_HOME to point to a specific hadoop install directory
export HADOOP_HOME=I:\develop_software\hadoop-2.7.7

# Hive Configuration Directory can be controlled by:
export HIVE_CONF_DIR=I:\develop_software\hive\apache-hive-2.1.1-bin\conf

# Folder containing extra ibraries required for hive compilation/execution can be controlled by:
export HIVE_AUX_JARS_PATH=I:\develop_software\hive\apache-hive-2.1.1-bin\lib

修改 hive-site.xml

</property>

hdfs上面建立文件夹

创建hive数据库，注意编码 latin1

在mysql服务器上新建一个数据库叫hive

然后启动hadoop

start-all.cmd，没错，hadoop也装在windows

然后启动建表，命令： hive --service metastore

看到下面这个地方的话建表就成功了

诺

测试一下

运行 hive.cmd

创建一张表

hive> create table test_table(id INT,name string);

hive> show tables;

然后在show tables后的信息打印了很多，一直拉下去，能看到test_table，那么我们就装成功辣。

当然，hdfs上肯定也有了
